What is non-alloy steel?
Steel is often called carbon steel due to the mixture of carbon atoms with iron atoms. The added elements provide the steel with ductility and strength. During the smelting process, other elements such as aluminum are added to the steel, making it an alloy steel. Non-alloy steel is smelted without any added elements.
Application areas
Non-alloy steels can be used in different applications. The steel bars used to reinforce concrete are non-alloy steels. Wrought iron is another type of non-alloy steel because iron ore contains almost no carbon. Wrought iron is soft and easily worked into different shapes, but has little strength. Non-alloy steel is often used to make decorative metal gates and fences.
